Description

[Detailed description of the invention]

The present invention relates to a transmission/reception control method for a remote control device that controls the operation of a controlled machine at a remote location. Conventionally, in a transmitting device of a remote control device, in order to remotely control multiple control contents of a controlled device,
There are multiple selection switches for each control content, and after the user selects and operates the appropriate mode, the user operates the switch that starts transmission, and the transmitting device receives this and sequentially converts each control content into a signal. , devices that transmit using various propagation signals such as wired or wireless (hereinafter referred to as preset type transmitting devices) have been developed. Therefore, it is possible to provide the convenience of being able to confirm at the time of transmission or after transmission at the transmitting device. This can be used to remotely control air conditioners such as room coolers, for example.
It can be seen in transmitting devices for wireless remote control devices that use light. However, all conventional reception control devices simply receive received signals and remotely control the operation or mode of the controlled device, and if the control signal becomes unreceivable due to noise etc. during propagation, All the contents of one transmission were canceled, and in this case, the controlled machine could not be remotely mounted. For this reason, remote control has not been practical in situations where the transmission/reception distance is relatively long or there is a lot of noise. Conventionally, when doing this, it was necessary to reduce the content of each transmission and to perform reception control on the receiving side each time to reduce the probability that noise would enter the transmission and reception. This means that
This requires the user to perform a complicated transmission operation, which is inconvenient. In addition, when the power of the receiving device is turned off and on, the controlled device does not start moving, especially when the above-mentioned single transmission content is canceled, and in the method described later, all modes are operated completely. Due to this necessity, many switch operations were required, making it extremely complicated. The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology, and it is possible to employ an easy-to-operate preset type transmitter as a transmitter, and to transmit the contents of one transmission according to a normal signal and detect abnormal parts. teeth,
It is possible to perform remote control with a function to control the operation of the controlled machine according to the contents received normally last time, and to prevent malfunctions. The purpose is to provide a highly practical remote reception control method, such as being able to perform remote control such as automatically determining various other modes within an appropriate range and operating the controlled machine for the time being as long as information can be received. That is. An embodiment of the present invention will be described below with reference to the drawings. In one implementation of the present invention, one control content is the operation or stopping of the controlled machine, and the control content of devices B and C in the controlled machine is set to one or three modes, respectively, and the control content and It is said that FIG. 1 shows a preset type transmitting device according to an embodiment of the present invention, where 1 is the main body of the transmitting device, 2 is an operation switch that determines the control contents,
Reference numerals 3 and 4 indicate operation switches for determining control details, respectively, and 5 indicates a switch for starting transmission. Here, for example, the operation switch 2 is set to set the control content to operation, the operation switch 3 is set to set the control content to mode, and the operation switch 4 is set to set the control content to mode, and after that, By operating the transmission switch 5, control contents ~ are sequentially transmitted as one transmission signal. This transmission signal is shown in a timing chart in FIG. 2. As each transmission data, a signal that determines one control content is sequentially transmitted during a certain period of time T, and as the control content, the operation data 6 is Data 7 indicating that mode=is transmitted as the control content, and data 8 indicating that mode is equal to the control content are respectively transmitted. Here, the transmission switch 5 in FIG. 1 may also serve as the operation switch 2. In this case, the operation data 6 in FIG. It is also easy to make it mean a stop. Note that the configuration and detailed operation of the transmitting device that performs such transmission, the transmitted signal itself, and the propagation method are not the gist of the present invention, so illustrations and explanations will be omitted. Now, the receiving device, which is the main feature of the present invention, will be explained in detail below using FIGS. 3 to 6. Note that the received signal is the transmitted signal shown in FIG. 2 described above, and since the transmission and reception in other various modes are the same, their explanation will be omitted. FIG. 3 shows a block diagram of a receiving apparatus in an embodiment of the present invention, in which 9 is a reception input means, 10 is a data memory, 11 is a controller, 12 is a control means, 13 and 14 are controlled devices, and 15 is a Various explanation input means are shown. Here, the aforementioned transmission signal is received by the reception input means 9, converted into a signal that can be received and processed by the controller 11, and sent to the controller 11, and the controller 11 receives this, The control means 12 exchanges various data with the data memory 10 in predetermined cases, and based on the result of a predetermined judgment procedure.
It is output for. In response to this, the control means 12 drives the power supply of the controlled devices 13 and 14 or the main body of the controlled device having these controlled devices 13 and 14. The setting input means 15 performs various initial settings and notifies the controller 11 of the settings.
A detailed explanation of the operation will be given later. Hereinafter, the same parts will be denoted by the same symbols and the explanation will be omitted, and the same will apply to parts unrelated to the present invention. The transmission signal shown in FIG. 2 will be explained in detail below using FIGS. 4 to 6 as an example. FIG. 4 is an electronic circuit diagram of a receiving device according to an embodiment of the present invention, in which 16 is a microcomputer (hereinafter simply referred to as a microcomputer) serving as the data memory 10 and the controller 11;
31 is a power source for the main body of the controlled machine. This microcomputer 16 is composed of a ROM, RAM, various input/output ports, etc., and includes the receiving input means 9.
Pass the received signal through resistor R1 in a more readable form.
The signal is received from the iNT input terminal, and an appropriate output is sent to the control means 12 through each of the output ports E0 to G2 through a predetermined procedure. Further, the setting input means 15 provides initial set values for each mode from each input port B0 to C1, which are used as initial values in this procedure. The control means 1
2, inverters 17-23, relays 24-30
By receiving the output from the microcomputer 16 and driving the corresponding relays, the main body of the controlled device is stopped and the controlled devices 13 and 14 are controlled. The setting input means 15 is composed of jumper wires J1, J2 and resistors R2 to R5.
1 and J2, a predetermined initial set value is output to the microcomputer 16 for each mode. Note that the reception input means 9 may include a PIN diode, a detector,
It is composed of a tuner, a waveform shaper, etc., and this configuration is almost uniquely determined by its transmission form, as is well known. However, the detailed configuration and explanation thereof are the same as those of the microcomputer 16, and the power supply circuit of the receiver is not the gist of the present invention and can be easily accomplished using well-known techniques, so they are not shown and the explanation will be omitted. Next, the operation will be explained using the flowcharts shown in FIGS. 5 and 6. Both figures show a predetermined procedure carried out in the microcomputer 16 and briefly explain the reception control method of the remote control device of the present invention. At the beginning of its operation, the microcomputer 16 first clears all data memories,
Waits for input from the transmitting device. At the same time, input is made from the setting input means 15 through the B port and the C port, the state of the jumper wire is read, the setting is set as shown in Table 1, and the contents are decoded based on this. Control contents and control contents are stored in memory in advance. These various types of memory actually refer to internal RAM in fixed locations.

[Table] When a received signal is received, the signal is input from the iNT input terminal, and in this embodiment, it is processed as an interrupt, and the received signal is decoded using a predetermined method. For example, if "0" and "1" are sent as signal lengths, all you have to do is measure them, and the configuration for this is almost sufficient with the microcontroller, and well-known technology is sufficient. Since this is easily possible, and is not the gist of the present invention, illustrations and explanations will be omitted. The decoded results are then stored in a work memory for reception (hereinafter simply referred to as reception memory). Next, as shown in FIG. 6, the microcomputer decodes the contents of the reception memory and first determines whether it is a normal signal. If the result is a normal signal, it is classified, stored in various data memories, and its contents are updated. Furthermore, if the signal is not normal, only the reception memory is cleared without updating. At this time,
Setting the contents of the operation memory other than operation control signals to be processed only during operation will help prevent unnecessary changes and malfunctions when the controlled machine is stopped, and this is also done in this embodiment. After processing these received signals, clear the contents of the reception memory,
The contents of the operation memory, control contents, and control contents memory are sequentially read out and outputted to the E, F, and G output ports in accordance with the contents. In response to this output, the control means 12 operates or stops the main body of the controlled machine, or controls the controlled equipment 13, 14.
Change the mode. Here, the operation and stop of the above-mentioned control contents is performed by turning on the E0 output port. When the relay 24 is turned off, the relay 24 is turned on. The above-mentioned control contents are realized when the corresponding output ports F0 to G2 are turned on. This is realized by turning off, and as a result, it comes to be controlled by the settings of each operating switch of the transmitting device. By repeating the above-mentioned series of processing steps, the desired remote control was achieved. If the same received signals are obtained with the transmission data shown in Figure 2, and all the signals are normal, the first operation signal is input to the iNT input terminal, and as a result, the reception The operation signal is set in the memory, and since it is a normal signal, the same contents are set in the operation memory. Afterwards, the reception memory is cleared, and the operation signal is taken out from the operation memory and sent to the E0 output terminal, whereupon the control means 12 receives it and supplies power to the main body of the controlled machine to start operation. Soon, the next = signal is received, input again from the iNT terminal, and this time the = signal is set in the reception memory. Since it is also a normal signal and because the vehicle is in operation, the same signal is set in the memory of the control contents. As before, the reception memory is cleared, and this time, the same signal read from the control content memory causes F0, F
By resetting both output terminals of F1 and setting the F2 terminal, the controlled device 13 is fixed in the mode. The next = signal is also processed in the same manner as above, and the controlled device 14 enters the mode. Therefore, if each signal cannot be received normally due to disturbance such as noise, each signal is ignored, the contents of each memory are retained, and no malfunction occurs. Now, if only the operating signal can be normally received during the first reception after the receiving device is started up, the setting input means 15 is set in advance according to the contents of each data memory that has been reset in the initial stage. Then, the controlled machine starts operating. In one embodiment of the present invention, the received signal from the reception input means 9 is input to the iNT of the microcomputer 16.
Although input to the terminal is processed as an interrupt, any other method that can be captured by a microcomputer, such as a 2-wire or 3-wire handshake method, may be used, or even if it is not a microcomputer, the above-mentioned method can be used. It is also possible to use an LSI that has certain functions.
In addition, in the setting input means, if you do not want to make such a selection in advance, you can incorporate the setting into the program and use external jumper wires, etc.
If you want to eliminate various parts and have relatively freedom in selection, use the jumper wires J1 and J.
You can use point 2 as a switch. Naturally, it is also easy to make the data memory capable of backing up and eliminate the adverse effects caused by turning the receiving device on and off. It goes without saying that each control content may not be directly output to the output port, and it is also possible to determine the content of the transmitting device and the transmission propagation format (wired or wireless using light, sound, radio waves, etc., serial or parallel signals). ) may be any, and any of the above cases does not depart from the gist of the present invention. As described in detail above, according to the transmission/reception method of the present invention, it can be realized with a simple configuration of a reception input means, a data memory, a setting input means, a controller, and a control means, and provides a preset with excellent operability. It is highly practical and flexible, not only because it allows the use of a type transmitter and has many advantages in its actual use, but also because it prevents malfunctions and is effective even during start-up. It is extremely useful and convenient for remote control, especially between relatively distant locations or under noisy conditions. Moreover, since a preset type can be used for the transmitter, the user can check each transmission mode at a glance during or after transmission, and the operation is simple and extremely convenient.
